First knight odds match with IM Saturday

[carldaman]

Thanks, the link did work. I don't how I could've found the live game without it.

[lkaufman]

First game (g1 odds) was a crushing win by Komodo. Ray played natural looking moves, no simple blunders, but soon faced a crushing kingside attack. Game two (b1 odds) underway now.

[lkaufman]

Second game (b1 odds) was also won by Komodo, but not so easily. Ray traded his extra knight for a two pawns up endgame, but had poor development and a bad bishop. He should have at least held the draw, but it was too difficult with short time.

[lkaufman]

Third game something strange happened. Play reached an obviously drawn rook and knight (Ray) vs rook and pawn endgame, tablebase draw, and Ray naturally offered a draw. I had no way to accept for playkomodo, and for unknown reasons it just froze and refused to move until time ran out, then disconnected. I don't know if the draw offer caused the problem, or the tablebase position, or if it was just a random disconnection. Anyway although it is officially a win for Ray, for our purpose of judging where Komodo stands at knight odds it was a draw. We'll figure out what the problem was with time.

Note the comment to move one, where 1Nh3? is said to cut the handicap in half compared to 1Nf3!! This shows just how horrible the NN engines are when down a piece (11248 and relatives exempted). Better to use stockfish or Komodo to analyze knight odds games.

[lkaufman]

Fourth game similar problem. Komodo allowed Ray to reach rook and two pawns vs rook because it was a TB draw, but once there it just refused to move and timed out. No draw offer involved, so it's clearly related to TB, and it doesn't seem to happen on my own pc, just on chess.com. Anyway official score 2 to 2, but with TB adjudication it would be 2 wins for K and 2 draws.

Hi Larry
When will the Musketeer Komodo Engine released ?

Game 3: Ray remained a knight ahead well into the endgame with only the bishop pair as compensation for Komodo, but Komodo managed to exchange Ray's last pawn to reach an obviously drawn rook and pawn vs rook and knight endgame, TB draw.

Ray offered a draw here but we had no way to accept it, and although Komodo knew it was a TableBase draw, it refused to move and timed out here for unknown reason.
